摘要

The process and the island of production of a product plan of cold rolled steel of stainless steel. The invention relates to a process and a production line (1) for the production of a product and steel (cold rolled and) of a tape hot (W), which consists of stainless steel, carregda a crust of iron oxide.In the process according to the invention, the tape hot (W) loaded with a crust of iron oxide, it is cold rolled to the product plan of steel (and), the product plan for cold rolled steel (and), obtained after cold rolling of hot strip (W), it is made in the state hard The rolling mill, before annealing, a pickling treatment.In which the crust iron oxide existing on the product plan for cold rolled steel (E) is mechanically removed. In this way, the processes of production lines may be implemented, with which it is possible to perform economical way flat products of steel cold-rolled, of stainless steel. With the condition of the surface improved.
